Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a protective busbar that avoids electric arc. Background Technology

[0002] Busbar trunking is a closed metal device composed of copper or aluminum busbar columns. It is mainly used to distribute large power to various components of a distributed system. It has gradually replaced wires and cables in indoor low-voltage power transmission trunk line projects and is widely used in electrical equipment and power systems in high-rise buildings and factories. With the emergence of modern engineering facilities and equipment, the electricity consumption of various industries has increased rapidly, especially with the emergence of many high-rise buildings and large factory workshops. Traditional cables, as transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Plug-in busbar trunking, as a new type of power distribution conductor, has emerged. Compared with traditional cables, it fully demonstrates its superiority in high-current transmission. At the same time, due to the adoption of new technologies and processes, the contact resistance and temperature rise at the connection points of the two ends of the busbar trunking and the plug-in points of the branch ports are greatly reduced. High-quality insulation materials are used in the busbar trunking, thereby improving the safety and reliability of the busbar trunking and making the entire system more complete.

[0003] Existing busbar protection devices have relatively simple structures and are not very effective at preventing electric arcs. Some devices that prevent electric arcs have complex structures and high costs, which leads to certain limitations in the use of existing busbars. Utility Model Content

[0004] The purpose of this invention is to provide a protective busbar trunking that avoids electric arcs, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective busbar trunking system to prevent electric arcing, comprising a busbar trunking body,

[0006] A connecting block fixedly installed on the side wall of the busbar trunking body;

[0007] A connector that is fixedly installed at the other end of the connecting block;

[0008] And protective components are provided on the side of the busbar trunking body;

[0009] The protective assembly includes a protective mechanism disposed on the side of the busbar trunking body;

[0010] An auxiliary mechanism is provided on the side of the busbar trunking body, and the auxiliary mechanism is connected to the protective mechanism.

[0011] Preferably, there are two connecting blocks, and the two connecting blocks are of the same shape and size.

[0012] Preferably, the protective mechanism includes a rubber top plate and a connecting slider. The side wall of the connecting slider is connected to the inner wall of the connecting block with a circular groove. A protective side plate is fixedly installed on the side wall of the connecting slider. The top of the rubber top plate is in contact with the rubber top plate. A positioning bolt is rotatably installed on the inner wall of the rubber top plate. The bottom of the positioning bolt is threadedly connected to the inner wall of the connecting block with a positioning hole. When the positioning bolt rotates, one end can be installed into the positioning hole inside the connecting block.

[0013] Preferably, the bottom of the rubber top plate is in contact with the top of the protective side plate, and the bottom of the rubber top plate is in contact with the top of the connecting block.

[0014] Preferably, there are three rubber top plates, and the three rubber top plates are all of the same shape and size.

[0015] Preferably, the auxiliary mechanism includes a stabilizing connecting plate, the side wall of the stabilizing connecting plate is in contact with the side wall of the connector, a bolt is rotatably installed on the inner wall of the stabilizing connecting plate, one end of the bolt movably penetrates the inner wall of the connector, and a nut is threaded onto the side wall of the bolt.

[0016] Preferably, there are multiple bolts, and the multiple bolts are evenly distributed on the side wall of the stabilizing connecting plate.

[0017] This invention provides a protective busbar trunking system to prevent electric arcing. It has the following beneficial effects:

[0018] (1) This utility model allows operators to install the connecting slider into the inner wall of the circular groove inside the connecting block, thereby quickly installing the connecting slider and the protective side plate. Then, the rubber top plate is installed on the top of the connecting block, and then the position of the positioning bolt can be rotated directly. Since one end of the positioning bolt is threaded to the inner wall of the positioning hole, the position of the rubber top plate can be quickly installed. The rubber top plate and the protective side plate can prevent the generation of electric arc, improve the performance of the busbar trunking, and solve the problem that the existing busbar trunking protection device has a relatively simple structure and poor protection effect against electric arc. Some devices for preventing electric arc generation have complex structures and high costs, which leads to certain limitations in the use of the existing busbar trunking.

[0019] (2) When the operator connects the connectors, the connectors are first mated together, then the stabilizing connecting plate is installed on the side wall of the connector, then the bolt passes through the inner wall of the connector, and then the nut is rotated. Since the inner wall of the nut is threadedly connected to the side wall of the bolt, the position of the stabilizing connecting plate can be stabilized by rotation, thus effectively stabilizing the position of the two busbar trunking bodies.

[0027] Example 1: A preferred embodiment of the arc-avoiding protective busbar trunking provided by this utility model is as follows: Figures 1 to 5 As shown: A protective busbar trunking system for preventing electric arcing, comprising a busbar trunking body 1,

[0028] There are two connecting blocks 2, which are fixedly installed on the side wall of the busbar trunking body 1. The two connecting blocks 2 are of equal shape and size.

[0029] Connector 3 is fixedly installed at the other end of connector block 2;

[0030] And a protective component 4 is installed on the side of the busbar trunking body 1;

[0031] The protective component 4 includes a protective mechanism 41 located on the side of the busbar trunking body 1;

[0032] An auxiliary mechanism 42 is provided on the side of the bus trunking body 1, and the auxiliary mechanism 42 is connected to the protective mechanism 41.

[0033] The protective mechanism 41 includes a rubber top plate 411 and a connecting slider 414. The side wall of the connecting slider 414 is connected to the inner wall of the connecting block 2 with a circular groove. A protective side plate 412 is fixedly installed on the side wall of the connecting slider 414. The top of the rubber top plate 411 is in contact with the rubber top plate 411. A positioning bolt 413 is rotatably installed on the inner wall of the rubber top plate 411. The bottom of the positioning bolt 413 is threadedly connected to the inner wall of the connecting block 2 with a positioning hole. When the positioning bolt 413 rotates, one end of 413 can be installed into the positioning hole inside the connecting block 2.

[0034] In this embodiment, the bottom of the rubber top plate 411 is in contact with the top of the protective side plate 412, and the bottom of the rubber top plate 411 is in contact with the top of the connecting block 2.

[0035] Furthermore, there are three rubber top plates 411, and the three rubber top plates 411 are all the same in shape and size.

[0036] In the specific implementation process, the operator installs the connecting slider 414 into the inner wall of the circular groove inside the connecting block 2, thereby quickly installing the connecting slider 414 and the protective side plate 412. Then, the rubber top plate 411 is installed on the top of the connecting block 2, and then the positioning bolt 413 can be rotated directly. Since one end of the positioning bolt 413 is threaded to the inner wall of the positioning hole, the rubber top plate 411 is quickly installed. The rubber top plate 411 and the protective side plate 412 can prevent the generation of electric arc and improve the performance of the busbar trunking.

[0037] Example 2: Based on Example 1, a preferred embodiment of the arc-avoiding protective busbar trunking provided by this utility model is as follows: Figures 1 to 5 As shown: The auxiliary mechanism 42 includes a stabilizing connecting plate 421. The side wall of the stabilizing connecting plate 421 is in contact with the side wall of the connector 3. A bolt 422 is rotatably installed on the inner wall of the stabilizing connecting plate 421. One end of the bolt 422 moves through the inner wall of the connector 2, and a nut 423 is threaded on the side wall of the bolt 422.

[0038] In this embodiment, there are multiple bolts 422, which are evenly distributed on the side wall of the stabilizing connecting plate 421.

[0039] In the specific implementation process, when the operator connects the connector 3, the connector 3 is first mated together, and then the stabilizing connecting plate 421 is installed on the side wall of the connector 3. Then, the bolt 422 passes through the inner wall of the connector 3, and then the nut 423 is rotated. Since the inner wall of the nut 423 is threadedly connected to the side wall of the bolt 422, the position of the stabilizing connecting plate 421 can be stabilized by rotation, effectively stabilizing the position of the two busbar trunking bodies 1.
